 So I have opened core-pagination.php, and this is what it says:

 09: * @since Optimizer 1.0
 10: */
 11:global $optimizer;?>
 12:
 13:<?php function optimizer_pagination($navigation='numbered', $query='')
 { ?>
 14:
 15:             <?php if($navigation !== 'no_nav') { ?>
 16:
 17:                <?php if($navigation == 'numbered' || $navigation ==
 'numbered_ajax') { ?>
 18:                    <div class="ast_pagenav">

 im still not sure what the error is with line 13, any help would be much
 appreciated!
